Problem is, property prices make that non feasible. Most companies tend to cluster around the same locations, so a lot of people want to buy or rent property nearby and eventually the prices simply become unaffordable. You can't build upwards or downwards indefinitely, and you can't build too far outwards because the 5-10 miles thing goes away, so people will always have to commute to their workplace. The population is too high and the amount of space too limited to make this a reality, at least in countries with a decent sized population.
